Specification ofLetters Patent. Patented Jun 19,1911

Application filed anuary 22, 1915. Serial no. 3,763.

To all whom it may concern Be it known that I, FRANCIS A. NOLAN,

a' citizen of the United States, residin at St..Paul, inthe county of Ramsey and tate of Minnesota, have invented a new and useful Improvement in Stops for Sound-ReproducingMachines, of which the following is a specification, p

The primary object of this invention is the production of a simpleand inexpensive stop which can be easily and quickl applied or automatically setting the, brake and stopping the ich. the record is carried immediately when the playingkof a record is completed. further object is the production of a device of its; kind, which can be attached to machine without" the sound reproducing or reconstructmg any of the mechthelatter.

Astill further object is to. provide a device of the kind stated, which will stop any.

record immediately hen a predetermined point near the on of the sound groove is reached by the stylus or sound box and which attached toor detached from the machine. To. theseends my invention consists of the features of construction and combinations ofparts, which will be hereinafter more particularly described and set; i

is a side view of a detail of the construction in 's illustrating two of the commonly called E ison types, and one of the Victor type, it being understood that the invention can be'attached to other forms and is not confined to the particular types illustrated.

In the drawings, A designates the casin of a sound reproducing machine, in whic is contained a motor not illustrated of usual type for revolvin the turn table B, said casinghaving revo ubly mounted thereupon by means of the vertical shaft C, the usual amplifying horn or tube, the small end of which extends upwardly through the opening E or slOt in the top of thecasin and projects forwardly over the turn tab e and carries u on its forward'end the usual sound ,box F. laced upon the top of the casing is the brake device G, which may be of any desired construction, that illustrated consistthe turn table to revolve freely. adjlacent the bell crank lever is a 1 consisting of an arm 8 pivotpermitting ositione releasable catc ed by the pin.9 on

1e to stop the latter from re-- p the top of the casing and having its inner end provided with a shoul der 10, which is adapted to engage in a notch '11 in the hub portion, of the bell crank lever to lock the bell crank the arm. 8 pro ects beyond the the turn tablein position, so t can be turned upon I sion spring 12 secured to the arm 8 an the bell crank lever 'as illustrated tendsto hold the-catch engaged with the bell crank lever. Upon; releasing the notch- 11 by turning a t m the .arm 8 the spring immediately'turns the'bell crankleverfan forces theshoe 5 against the flange 6 of the turn table and stops the machine. -'1.his;part of the mechanism can when desired, the, starting of the be operated by-L hand accomplished by swingin with t e 5 ba k the" bell th itspivot. The com 'resa hine lever With its brake The outer end of pieriphery of shoulder. 10 fromflthe chine being accomplished by pressing the same and releases it from e catch arm until it releases from engagement with the bell crank, whereu on the shoe 5 presses upon the flange 6 .an stops the turn table.

My lmproved adjustable stop may be applied to the'shaft, journal or turninoportion of the amplifying horn. its mode ot application and construction being varied to suit the requiren'ientsv of the design and form of apparatus to which it is desired to apply ,the invention. As illustrated in Figs. 1 to 5,"thc pivot shaft C projects above thetop of/ the casing and to its upward projecting portion 1s secured a radiating arm l'lfwhich tapers outwardly toward the turn table in front of the outwardly projecting portion of the catch arm 8. The sound reproducing machine thus far described to which my invention is applied is the conventional Edison type of machine. To this radiating arm H which turns with the'shaft C is detachahly secured a. support 15 in the form of a narrow plate having down and inwardly turned clips 16, which slide and engage over the edges of the arm H and hold the support 15 firmly secured on said arm. The outer end of this arm carries an eccentric disk 17. which is pivoted by means of the screw 18 passing through said disk and threaded into engagement iyfvitli said 511' port. This eccentrio disk is"fpo sition e'd'1n the path of the outer end ofjthe releasable catch arm 8. so that as the piyfot shaft C turns said disk approaches the arm 8 untiliit strikes the the brake, whereupon the b ake stops the turn table.

It will thus be observed that according to the position into which the eccentric 'is turned, the time at which the disk is stopped is varied and as the sound record grooves-in record disks such as I vary in length, it is desirable to set the eccentric so that it will at a predetermined time. Accordingly t e disk'17 is prQ'Yided on its face with a graduated scale 1-9 arranged concentric with the pivot screw 18, upon which the eccentric is journaled,

and in order to hold the disk set in selected position, a series of ratchet teeth 20 are also formed infthe disk in a circle concentric with said ivot screw and scale. A spring dog 21 havlng a downwardly tapering catch shoulder 22 sweeps over and engages with said teeth to hold'the eccentr1c-pos1t1oned.

The markings on the scale 19 Wlll indicate according to markings such as 23 previously placed upon the record diskthe position in which the eccentric 17 shou'ld be adjusted below the dog 21 to stop the reeord, as soon v as it has been played. Thedog 21 is in the form of spring arm pressingdownwardly agement with 4 fre end of the dog '21 below the head of tlic screw 18, and by its opposite end upon the support 15 by means of the screw 25. The

free end of the dog 21 is formed in the shape of a pointer. which is tltlilplfttl to indicate on the scale 19. the number to which the eccentric disk should be moved to correspoml witht-henumberor marking upouthc record. The number of ratchet teeth 20. with which the shoulder '22 on. the dog- L! engages may serve to determine thepositiou into uhich the stop disk 17 is turned by counting or by feeling or hearing the number of click made. Thus my improved slop may be accurately positioned lgy observing the numbers. or fractious lherci'd; on the dial. as when the device is played in a lighted room:

or by listening to the number of clicks ul" feeling the impacts made as the disk is set. as may be. necessary when the device ls plaved in dark or unlighted room.

his attmrlnucut can easily he placed upon the arm ll for use or removed when desired and its simplicity. .which is reduced to a 'the changes permitting minute adjustment ofthe disk to stop the record at the exact position desired.

In the construction of sound reproducing machine illustrated in Figs." TIS and lot the drawings my improved adjustable stop is applied to the pivot shaft C in the same manner as illustrated in Fig; 1 above described; The amplifying horn is fed positively in the usual manner sucl1 as by the feed screw 30 extending from the motor '81 with its teeth in mesh with the feedquadrant 32, thus adapting the sound box as illustrated in Fig. 1 to be positively fed when playing from the usual Iidison record.

"When 8. Victor record is played, the sound box J is attached to the sound conducting tube 33 through the medium of a universal loo connection 34, 35, the connection being.

joined at one extremity to the reduced forwardly projecting portion ofthe amplifying horn and at 1t s other extremity to the sound box, as shown, said joint ermittin free lateral and vertical motion 0 the soiln box. By. this means, the sound boxis fed automatically by the grooveitself of being fed synchronously with the record movement of the arm and holds it in blocking position in the path ofthe portion of the amplifying horn projecting up through the passage 41 in the top of the casing. These arms are distributed to determine the startin point of the swingingamplifying horn. or instance when a ten inch or small sized record is played, the arm 37 is .swung into outermost position, and the hornset to start feeding by being movedagainst said arm and When a 14 inch or large sized record is played, the arni 37 is swung down,

and the arm 36 swun out as illustrated in- Fig. 7, and the ampli ying horn moved into the position illustrated in Fig. 7 against the arm 36. During the subsequent playing of the record, the motor 31 causes the feeding mechanism to feed the sound amplifying horn ositively and the freely disposed sound ox is adapted to automatically feed forwardly by engagement with the record groove in the disk partly independent of the forward positive feed of the horn. By this construction my improved automatic stop L- similar in construction to that employedas illustrated in Fig. 1 is adapted to accurately stop the revolution of the turn table precisely at the end of the record ,which-is played. The disclosures presented in Fig. 7 are patterned after the conven-- tional machinenow on the market and, of

course, no claim is made thereto, it being shown and described somewhat in detail so that the operation of my improved stop may be readily understood.

In Figs. 10 and 11 details of the ordinary Victor sound reproducing machine are illustrated, 45 indicating the sound arm, which is swiveled at46 upon the to of the casing 47, to swing horizontally an laterally. 48 indicates the usual sound box mounted upon the'tube 49, which is swiveled in the free endof the. arm'45 at 50 to swing freely up and down. In this construction, the record such as 51 is adapted by its sound groove beingfengaged'by the needlein the sound box to feed the sound box automatically .while the.machine is in operation and my improved adjustable stop is attached to the shaft, journal or turning portion of the in t e manner a ove set forth. .The adjustable stop has itssupfporting arm 55, carrying the eccentric 56 ormed w th a p i collar 57, which is clamped around the elbow portlon of the sound conducting arm 45 by means of the bolt 58. The support 55 carries the frame. 59, which is formed with the.

dog member 60, similar to the part 21 illustrated in Fig. 1, which performs the same function of' releasably engaging the teeth trated in Fig. 1 and the eccentric 56 "po sitionecl by the arm 45,- so as to strike the release member 62 and cause the brake shoe .63 to impinge against the rim 6% of the turn table 65 and stop the table from revolving at a predetermined time. v The adin the manner stated in connection with the description set forth in Fig. 1 deternnnes the exact point during the playing of a record at which the turn table is stopped.

The stop also by its scale is adapted to register the point at which the record should be stopped and the records can subsequently be marked accordingly by pasters or other means of identification. A chart can easily be kept showing the marks upon the records and from which it can be determined in advance at what point the eccentric should be set to stop the machine for any records The marks can be imprinted in the records, as they are made when desired.
